Coronary Artery Bypass Graft
Restoring Vital Blood Flow to Your Heart
A coronary artery bypass graft (CABG) is a specialised surgical procedure used to treat severe coronary artery disease. During the operation, a healthy blood vessel—commonly taken from the chest, leg, or arm—is attached to the coronary artery beyond a blockage. This creates a new pathway, or “bypass”, allowing oxygen-rich blood to reach the heart muscle. In Singapore, CABG is an established treatment for patients with multiple narrowed arteries or complex blockages that cannot be fully managed with medication or angioplasty alone.
Why Consider a Coronary Artery Bypass Graft?
When coronary arteries become significantly narrowed due to plaque build-up, the heart muscle may receive insufficient oxygen, causing chest pain (angina), shortness of breath, or increasing the risk of a heart attack. A coronary artery bypass graft may be recommended to help alleviate these symptoms, improve circulation, and reduce the risk of future cardiac events. Following the procedure, many patients notice an improvement in their ability to engage in daily activities and maintain an active lifestyle.

FAQs
Most patients stay in the hospital for five to seven days after surgery. Full recovery usually takes six to twelve weeks. During this time, participation in a supervised cardiac rehabilitation programme is recommended to gradually rebuild strength and support heart healing.
Yes. CABG is a major surgical procedure performed under general anaesthesia, ensuring the patient is unconscious and free from pain throughout the operation. Vital signs are closely monitored by the surgical team and anaesthesiologist.
As with any major surgery, risks include bleeding, infection at the incision sites, or reactions to anaesthesia. Modern surgical techniques in Singapore are designed to minimise these risks, and your surgeon will discuss your personal risk profile based on your age and health conditions.
Yes. Most patients continue taking medications long-term to maintain the health of the graft and reduce plaque build-up. This may include anti-platelet medications such as aspirin, cholesterol-lowering statins, and blood pressure medications.
CABG results are generally long-lasting, but the surgery does not cure underlying coronary artery disease. To help ensure the bypass remains effective, patients should follow a heart-healthy lifestyle, including a balanced diet, regular exercise, smoking avoidance, and regular follow-ups with their cardiologist.
